Hi,
1.Make sure the below services can be started normally without errors.
-
- Cryptographic Services
- VSS service
- COM+ Event System service
2.Please run the below command to grant the permissions and try list writers again.
- Takeown /f %windir%\winsxs\temp\PendingRenames /a icacls %windir%\winsxs\temp\PendingRenames /grant "NT AUTHORITY\SYSTEM:(RX)"
- icacls %windir%\winsxs\temp\PendingRenames /grant "NT Service\trustedinstaller:(F)"
- icacls %windir%\winsxs\temp\PendingRenames /grant BUILTIN\Users:(RX)
- Takeown /f %windir%\winsxs\filemaps\ /a icacls %windir%\winsxs\filemaps\.* /grant "NT AUTHORITY\SYSTEM:(RX)"
- icacls %windir%\winsxs\filemaps\.* /grant "NT Service\trustedinstaller:(F)"
- icacls %windir%\winsxs\filemaps\.* /grant BUILTIN\Users:(RX)
3.please check if there are any error from Microsoft-Windows-CAPI2 in event log when we run “vssadmin list writers”.

Hope this can help you.
